"Once more, IN MOST IF NOT ALL OF THE DESERT SW WATERING AT NIGHT
PROVIDES PERFECT CONDITIONS FOR FUNGAL DISEASE AND IT"S SPREAD IN
TURF! "

Is that so? Well how about Arizona, is that desert SW enough? Here's
advice from Arizona State University College of Agriculture on how to
water a lawn in Arizona:

"When should I water ?
Be a night owl.
Night or early in the morning are the most effective times to water,
because wind and evaporation are lower.
High wind speeds distort sprinkler patterns and produce non-uniform
irrigation. "


Or how about this from a major sod producer in Arizona:

"However, when the temperatures begin to rise in the spring you may
need to begin watering every night, depending on the needs of the lawn.
"


Or from Colorado State Univ:

"Finally, avoid watering during the heat of the day. Water early in the
morning or in the evening. If you have an automatic sprinkler system,
water during the night; our climate is so dry that night watering
doesn't create problems unless you overdo it.


Sound like none of the experts have a problem with night watering or
believe it will lead to disaster. So, stop the baseless hysterical
shouting.
